General description

The 74LVC623A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 V or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 V or 5 V environment.

The 74LVC623A is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. This octal bus transceiver is designed for asynchronous two-way communication between data buses.

The control function implementation allows maximum flexibility in timing. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic levels at the enable inputs (pins OEAB and OEBA). The enable inputs can be used to disable the device so that the buses are effectively isolated. The dual enable function configuration gives this transceiver the capability to store data by simultaneous enabling of pins OEAB and OEBA. Each output reinforces its input in this transceiver configuration. Thus, when both control inputs are enabled and all other data sources to the two sets of the bus lines are at high-impedance OFF-state, both sets of the bus lines will remain at their last states. The 8-bit codes appearing on the two sets of buses will be identical.

Features

  • 5 V tolerant inputs and outputs for interfacing with 5 V logic
  • Wide supply voltage range from 1.2 V to 3.6 V
  • CMOS low power consumption
  • Direct interface with TTL levels
  • Inputs accept voltages up to 5.5 V
  • High-impedance when VCC =0 V
  • Complies with JEDEC standard JESD8-B/JESD36
  • ESD protection:
    • HBM EIA/JESD22-A114-B exceeds 2000 V
    • MM EIA/JESD22-A115-A exceeds 200 V.
  • Specified from -40 Cel to +85Cel and from -40 Cel to +125 Cel.
